Ending today, Macy's offers the Martha Stewart Essentials Classic Mattress Pad with prices starting from $9.99. Opt for in-store pickup to avoid the $9.95 shipping charge. That's tied with our Black Friday weekend mention, at least $20 off list, and the lowest price we could find. This machine-washable cover fits mattresses up to 18" deep. It's available in sizes from twin to California King.
